S.C. Code § 63-17-360
Except where the circumstances indicate it to be undesirable, in all cases where an application for support has been made, an effort should be made by the judge to restore harmonious relations between the husband and wife and to adjust the issues raised by the application through conciliation and agreement. Where an agreement for the support of the petitioner is brought about, it must be reduced to writing and submitted to the court for approval. Where possible, the court shall see both parties and shall inquire of each whether the agreement, which he must state to them, is what they have agreed to. If it is, and the court shall approve it, the court without further hearing may thereupon enter an order for the support of the petitioner by the respondent in accordance with such agreement, which shall be binding upon the respondent and shall in all respects be a valid order as though it had been made after process has been issued out of the court. The court record shall show that such order was made upon agreement.
